Topics for Upcoming Meetings

  • Missing Ptolemy Classes (ckru)
    • Should be talked about when cmot is around.
  • Layout Aids (bdu)
    • Should be talked about when msp is around.
    • Another e-mail will be sent to have people think about this. (#1525)

Out of Context (rvh)

  • The sync charts editor allows for labels to be displayed or hidden.
  • rvh would like automatic layout to react to that. The layout should not leave enough place for labels when they are not shown anyway. (#1516)

Demo (uru)

  • uru presents the Back Hoe model.
  • There are two commands mapped to Cmd+R I. This should be fixed. (#1517)
  • Layout sometimes fails to react to collapsing states. There already is a ticket for that.
  • rvh suspects that backhoe-solution.strl (to be found in the models folder) might not be the correct model. Wants to check if that's indeed the case. (#1518)
  • What method does uru use to find the most recently opened diagram? haf pressures him into using the methods he developed. (#1519)
  • There are Xtext exceptions in the error log.
    • uru is to fix the underlying error. (NullPointerException at SCDataComponend:250) (#1520)
    • haf wants to find out, why Xtext turns that into an InvocationTargetException. (#1521)

Tooling (cds)

  • cds talks about tooling he has been developing.
    • A command-line tool that extracts all Ptolemy demo models.
    • A KIELER plugin for viewing the debug output produced by Klay Layered.
      • There should instead be a unified interface for all algorithms to output intermediate results. A new viewer could be used to display those, automatically layouted. cds will add a Wiki page about his thoughts on this. (#1522)
  • Such tools that may be of interest to others should be put into a new folder inside the trunk: tools. cds writes an e-mail about this. (#1523)
  • Again, a discussion ensues about how to structure plug-ins.
    • rvh proposes tagging projects according to their status. (experimental, stable, ...)
    • haf opposes doing that with a simple folder structure in the SVN repository. Instead, he proposes project sets.
    • Project sets, though, must be continuously managed.
    • Project dependency management is mentioned.
    • The discussion is then postponed. Since this is a complex issue, a task force is to be founded that produces a good solution once and for all.
      • At least, the following people should be on the task force: haf, msp, chsch, cmot.
      • cds will send an e-mail inviting those interested to join the task force. (#1524)

Bio Layout (rvh)

  • Through Petra Mutzel, we may have gotten into contact with a biologist. Biologists obviously have fancy diagrams with lots of different formatting. We should at some point try to investigate if KIELER can be extended to support that kind of rich formatting.
